Abstract

Five-component high-entropy WPP alloys such as Cantor's CoCrFeNiMn alloy, which have a good combination of strength and plastic properties and have favorable prospects for practical use, have been actively studied all over the world for more than a quarter of a century. The article provides a brief overview of publications mainly by foreign researchers on the search for directions for changing (improving) the properties of these alloys and their practical application. Theoretical and experimental work has been analyzed, indicating the possibility of electronic structures in the formation of properties of high-entropy alloys. Studying the magnetic properties of wind turbines can provide important additional information about their electronic structure. Using the example of the WPP (CoCrFeMn)_1-xNi_x, containing five ferromagnetic elements, the evolution of the magnetic nature with a change in temperature is traced. Attention is drawn to the need to accelerate the large-scale practical application of WPP. The difficulties and constraints of the practical use of wind farms and ways to overcome them are shown. In this direction, an analysis of publications in the foreign press on ways to create a wind farm from waste (scrap) of the machine-building and metallurgical industries has been carried out. The structural and phase states and mechanical properties of wind turbines made of pure constituent elements and products containing stainless steel, nichrome, and cobalt alloys are compared.
